Algebra.Com's Answer #359340 by oberobic(2304)![]() ![]() ![]() You can put this solution on YOUR website! Two angles can be defined as 'a' and 'b'. \n" ); document.write( "They are supplementary, so: a+b=180. \n" ); document.write( "a = 2*b +30 \n" ); document.write( "Substitute \n" ); document.write( "2b + 30 +b = 180 \n" ); document.write( "3b = 150 \n" ); document.write( "b = 50 \n" ); document.write( "a = 2*50 + 30 = 130 \n" ); document.write( "or \n" ); document.write( "a = 180-50 = 130 \n" ); document.write( ". \n" ); document.write( "Answer: The two angles are 50 degrees and 130 degrees. \n" ); document.write( ". \n" ); document.write( "Done. \n" ); document.write( " |
